I don’t think the tuner can choose. OTA streams are whatever the station broadcasts and depend upon the compression level and content. I’ve notice all kinds of gB/hr over the years. When OTA first went digital they were 6-8gB/hr but have dropped since.

On a related note - don't some (or all) OTA tuners capture the entire channel, including all sub-channels? I swear that this used to be the case, at least for some tuners. But it wouldn't make sense for a 1GB/hr capture. I thought that a full OTA channel was 18Mb/s which was something like 8.1GB/hr.

I think it just picks the desired transport stream from the channel, although I don't see why it couldn't record all sub channels for a given frequency. It's all packet switched, right? I still use a single tuner card and Sage won't allow me to record more than one sub at a time within a given physical channel.

To the OP, just look at the video detail for a given recording. It'll tell you the resolution.

It's been turning into a pet peeve of mine how broadcasters are slicing and dicing the available bandwidth. A lot of sub channels aren't even watchable anymore. I think I feel a rant coming. Nope, just gas.
